PORTABLE BOOKRACK.

Application filed April 10, 1923, Serial No. 631,227.

To aYZ whom it may concern.

Be it known that I, EDWARD D. GREEDY, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and 5 State of Iowa, have invented new and useful Improvements in Portable Bookracks, of which the following is a specification.

This invention is designed to facilitate the handling of books or ledger binders and 10 particularly books and loose leaf ledgers used in connection with book-keeping or posting machines. With this structure a frame is provided preferably carried on rollers so that the whole may be readily 15 rolled into convenient position for use and into and out of a vault. In order to make it available for such movement and still give it capacity it is desirable to have a series of shelves for carrying the books with such a mounting as to be moved with book contents into and out of the frame. It is further desirable to have these move into and out of both sides of the frame and the pres- Fig. 2 an end elevation, partly in section, on the line 2-2 in Fig. 1.

Fig. 3 a section on the line 3-3 in Fig. 2. Fig. 4 a plan view of one of the book holders.

Fig. 5 a section on the line 5-5 in Fig. 2. 1 mark the posts of the frame. A top plate with flanged edges 2 is arranged over 40 the four posts of the frame and secured preferably by bolts 3. Side portions 4: extend across the sides of the frame and these are in the form of angle irons and are secured by rivets 5. Cross bars 6 extend 45 across the ends of the frame, being secured to the posts by rivets 7 Three rollers 8, 9 and 10 extend through a channel iron 11, the iron being provided with abearing plate 11". Shelves 12 are formed of sheet metal and 50 extend between the end angle bars 13. The angle bars 13 not only extend the width of the shelves but also to the rear of the shelves and between the rollers 8, 9 and 10, the shelves at the angle bars from one side be- 155 2 fi i the roller 8 and. 9 and thos a Figure 1 is a side elevation of the device, partly in section, on the line 11 in Fig. 2.

the opposite side between the rollers 9 and 10 so that when the shelves are moved into the frame these parts overlap the shelves. The angle bars have the ends turned down at 14k engaging the rollers 9 and-l0 so as to form a stop for the outward position of the shelves. The shelves operate over guide rollers 15 extending between the posts and guide lugs 15 so that when the shelves are pulled out to the position shown at the left of Fig. 2 the, fronts of the shelves are held between the rollers 15 and lugs 15 while the extensions of the angle bars 13 are held by the rollers 8 and 9 and 9 and 10. Thus the shelf has a perfect support both in and out of the structure so as to readily support books mounted on the shelves and permit of the movement of the shelves with the books in place. The shelves have the downward lip 16 at their outer edges which form stops against the rollers 15 so as to locate the shelves when moved into the frame.

Book holders having bases 17 are mounted on the shelves. These bases are preferably of sheet metal having out-turned edges 18 with outwardly extending flanges 19. Plates 20 are arranged along the sides of the edges 18 and these have slots 21 through which screws 22 extend. U-shaped bars 23 are secured by rivets 24- -on the edges 18 and on the plates 20 and extend upwardly at a slight inclination so as to readily hold an inserted book 22*. Slots in the plates 20 permit the moving of one of the bars 23 to accommodate different sizes of books. The holders are preferably pivotally mounted on the shelves and on the top of the frame at the position shown, the bases having openings 25 through which pivot pins 26 extend. This permits the swinging of the book so that the books may be more readily observed in use. It will be understood that the book rack as a whole may be moved adjacent to the bookkeeping machine, or the like. A shelf 27 is pivotally mounted on a rod 28 extending between the end posts. ported in a horizontal position by a brace 29. The brace 29 is carried by a hook 30 at the lower end of a bar 31. The bar 31 is secured to the channel 11 by a rivet 32 and forms a stop holding the rollers 8, 9 and 10 in place. By disengaging the brace 29 the shelf may be dropped down to a vertical position thus reducing the size of the rack as a whole so that it can be readily housed This shelf is sup-- will also be noted that while I have shown the deviceadapted for use from-both sides in vthe broader aspects of the invention it amay ebe forinecbwith the shelves at one side only.
